Undertaking this particular side quest will require you to head to the heavily-armed location known as Nellis Air Force Base, which is the Boomer-occupied location at the far northeastern reaches of the Mojave Wasteland. Getting there can be complicated and outright dangerous; our Walkthrough will have more details on getting there, specifically outlined during the mission Wild Card: Side Bets. When you've safely arrived and have free reign to travel wherever you want around the base, you'll want to seek out an older man named Loyal. You'll find him either at the base's gigantic hangar, or in his own mini-hangar-like home.

Either way, upon speaking with Loyal, no matter where you happen to find him, you'll be able to offer him some of your assistance, at which point he'll ask you to help him fix some of the solar arrays on the base, thus contracting you for this side quest. There's a solar array near the back end of the base, but some of the panels aren't working. With a high (65+) Repair skill, you can simply work your way back there and fix them by hand. Otherwise, you'll be required to head to another location to get the repairs underway. And that location is none other than the NCR-controlled HELIOS One power station, where the army controls a rather impressive, much larger solar array of their own. If you've never been to HELIOS One, you'll find it far to the south of Nellis, along the eastern side of the map. Vault 11 is to the north of it, while Gibson Scrap Yard is just to the south.

If you've never been to HELIOS One, you'll have to speak to the people at the front gate to gain entry (keeping in mind that if you're not getting along with the NCR, you'll have to blast your way through a whole bunch of people to have any hope of getting to the solar array field at the back of the building). If you're cordial with the NCR guards manned at HELIOS One, you'll also gain an unrelated Side Quest called That Lucky Old Sun. Either way, upon gaining entry to HELIOS One itself, meander your way to the back left side of the building, where you should find entry back to the Mojave Wasteland. However, the door in question, near a couple of NCR scientists, will actually lead to the backyard area of HELIOS One. Because of the fence that surrounds the plant, there's no other way to gain entry to the backyard. Thus, you'll have to head inside to get back outside.

You'll find a massive, impressive array of solar panels in the backyard, which are involved in the aforementioned unrelated quest. However, strewn around the working, upright panels are five downed, scrapped solar panels (these will be marked on both your map and your compass). What you need to do here is walk up to each and opt to salvage these parts (which will require a mere 20+ Repair skill). Simply find all five downed panels and salvage each one; believe it or not, the NCR doesn't care at all about these parts, so you're not technically stealing from them... at least not in the sense that they'll violently attack you, or that you'll risk ruining your reputation with them. Of course, if you had to violently break into HELIOS One in order to gain access to this array in the first place, than that's not a problem for you, since the NCR already hates your guts as it is.

Once you've claimed the five rogue, destroyed, and now-salvaged panels, it's time to return to Nellis Air Force Base, which you can do easily from the HELIOS One array via a simple quick-travel. Once you're back, follow your new compass instructions to reach the far less impressive array at the base. Ignore the computer terminal at the base of the concrete array, and simply walk up to the panels themselves. Identify the five broken panels and examine each one, opting to use the materials you found at HELIOS One to make the necessary repairs. Once that's done, there's nothing left to do but to find Loyal once more to let him know about the good news. Remember -- he'll be hiding out either at the hangar, or at his home. Impressed with your hard work, he'll thank you, and this brief and easy side quest will conclude thereafter.
